Abstract

This paper describes friction tests of 3D printing materials in vacuum. The tests were conducted on reciprocally moving samples placed in vacuum at temperatures of up to 130°C. The samples were made from commercially available 3D printing materials (SBS, ABS, PETG, PLA, NYLON SUPER CARBON 2). The dependences of the in-vacuum friction coefficient of the samples on the sample temperature and critical temperatures of using the samples in vacuum were derived. Polymers PETG, NYLON SUPER CARBON 2 can be used in friction assemblies operated in vacuum because these materials have a low friction coefficient at room and high temperatures. The lowest friction coefficient at room temperature and the greatest thermal resistance are exhibited by NYLON SUPER CARBON 2. The research results can be applied in manufacturing 3D printing devices parts for use in vacuum.

真空中3D打印聚合物的摩擦特性

摘要

本文介绍了3D打印材料在真空中的摩擦力测试。测试是在最高130°C的温度下在真空中往复移动的样品上进行的。样品由可商购的3D打印材料（SBS，ABS，PETG，PLA，NYLON SUPER CARBON 2）制成。推导了样品在真空中的摩擦系数与样品温度和在真空中使用样品的临界温度的关系。聚合物PETG，NYLON SUPER CARBON 2可用于真空操作的摩擦组件，因为这些材料在室温和高温下摩擦系数较低。NYLON SUPER CARBON 2表现出最低的室温摩擦系数和最大的热阻。
